Wolves - an Ecological Study
The wolves and moose of Isle Royale are known world-wide, and they are the focus of the longest-running study of a predator-prey system in the wild (over 50 years and ongoing). Both species are relatively recent arrivals to Isle Royale -- moose apparently swam to the island and established a population in the early 1900s, and wolves followed decades later after traveling over the ice from Ontario, Canada in the late 1940s. Annual monitoring of wolves and moose began in 1958 when Durward Allen of Purdue University began an ambitious "10-year" study of the wolf-moose relationship. This study continues today, under the direction of John Vucetich and Rolf Peterson of Michigan Technological University.

Isle Royale’s inland lakes are home to an amazing diversity of invertebrates. Freshwater clams, sponges, bryozoans, snails, and insects exist in an abundance of forms and in huge sizes not seen since the late 1800’s.
